ive heard this mentioned a few times recently, one being the green energy revolution will create a further 20,000 extra jobs, i often wonder how they work that out? but why do we need any extra industries or the jobs they create if at the moment there is such a shortage of workers in all sectors across the board ? Im old enough to remember the 1970s 3 day week and the recessions in the early 1990s, when we had major unemployment and interest rates at 16 percent, plus inflation in the 1970s-1980s? I just find it quite amazing today that full employment and major job vacancies exist ?
